ASTRA CURSOMETER

Even if you are standing perfectly still, from the Sun’s perspective you are moving at about 107,000 km/h. ASTRA CURSOMETER is an instrument for observing yourself in motion. Point your iPhone toward the sky to observe the direction, distance, and relative velocity of the Moon, the Sun, planets, stars, and comets.
